Personally, I think that a lens hood does more to protect the lens anyway.

Same here. I've never used a filter "to protect the lens" (as the salesman
always used to say when trying to sell me one) but almost always use a lens
hood, except on a lens with the front element well protected by the overhang
of the lens body like most macro lenses. And I've never yet had a scratched
or otherwise damaged front element ("never" meaning "since my first serious
camera in 1951").

The debate on whether to use a protective filter is a never
ending one. I'm of the "transparent lenscap" school; I'll
transport the lens with a filter in place. Then, unless
I'm shooting in adverse conditions (spray, dirt, etc) I remove
the filter.

On different occasions, I've had a front element or a filter
marked by flying grit. I've also had a couple of filters
get a nice coating of sea spray. I ended up rinsing them
in distilled water several items to get them clean; not
something I'd try on a "real" lens.

In the end, it's your equipment, your money, and your choice.

That makes sense as far as it goes, but if I were shooting in conditions
where there was sea spray I think I'd be more concerned about keeping the
whole camera in some sort of protective container, an underwater housing or
something close to that.
